- Surgical Robot: from Rigid to Flexible – a mechanical point of view
Surgical robots, represented by the da Vinci Surgical System, has been increasingly used in the operating theatres. Benefits of the robot include: increased precision, finer movement, improved dexterity, reduced tremor, better vision, capable of remote-operation, etc. These benefits are attributed to multiple factors, mechanical design, advanced control, imaging, communication, etc. Mechanical design or the structure is fundamental. It defines the reachable workspace as well as dexterity of the end effector. From the structure point of view, current surgical arms could be divided into rigid arms and flexible arms. Rigid arms, like the Endowrist instruments of da Vinci surgical system, contains a rigid slim shaft and a wrist. During the operation the shaft pivots about the trocar to reposition the end effector. The consequence is small internal workspace, large external operation space and possible tear of the incision. Flexible arms, on the other hand, could bend inside the cavity. This increases the workspace and alleviates the need for pivoting. For semi-flexible surgical arms the shaft is still rigid. At the distal end of the shaft is a flexible bending section. They are mostly used in MIS, LESS and SPA surgeries. When the shaft becomes flexible as well, the surgical arm could navigate through natural orifice and performing NOTES. Due to the benefits of flexible surgical arms, much effort has been devoted to developing flexible surgical robots globally. A few flexible surgical robots have received FDA approval. It is believed that in the near future, a lot more would go into the operating theatre. In this presentation, the current status of flexible surgical robots research will be introduced. Also, some of my research on flexible mechanisms will be shared.

- Current status of robotic head and neck surgery in Singapore
Robotic assisted head and neck surgery is a new surgical aramentarium in the management of both benign and malignant head and neck disease. Trans-oral robotic surgery (TORS) has been utilized in the resection of early T1/T2 oropharyngeal cancer, as well as removing deep-seated tumors such as parapharyngeal space tumors and supraglottic/hypopharyngeal tumors. Additionally, accessing thyroid nodules or benign tumors in the neck can be made from a remote access incision such as the trans-axillary or retro-auricular (or modified facelift). These new techniques open a new paradigm in the surgical management of head and neck diseases and the current adoption of the technology in an academic tertiary medical centre will be presented.
Dr Lim graduated from the Faculty of Medicine, National University of Singapore in 1998. He underwent residency in Otolaryngology in Singapore and was awarded the Gold medal for the MRCS (Edinburgh) General Surgery examination in 2003, and subsequently the Gold medal award by the College of Surgeons for the best performing resident in the exit examination organised by the Specialist Training Committee in Otolaryngology in 2009. After completing his specialist training, Dr Lim joined the Department of Otolaryngology – Head and Neck Surgery in NUH as an Associate Consultant. He started his practice and pursued further training in head and neck oncologic surgery at the National University Health System, Singapore. In 2010, he was awarded the Ministry of Health Overseas Training award and pursued a 2-year Head and Neck Oncologic Fellowship at the University of Pittsburgh Medical Center in the United States of America. This fellowship is accredited by the Advanced Training Council of the American Head and Neck Society. During these 2 years, Dr Lim did translational benchwork research in immunotherapy in head and neck cancer, focusing on immunological mechanisms in monoclonal antibody based therapy in cancer and identifying novel immune modifiers in cancer therapy. In his clinical training, Dr Lim was trained in transoral robotic surgery (TORS), minimally invasive video assisted thyroidectomy (MIVAT) and minimally invasive approaches in head and neck surgery, in addition to the major head and neck resections. Upon his return to Singapore in 2012, he was appointed Consultant at the Department of Otolaryngology – Head and Neck Surgery, NUH, and Assistant Professor at the Yong Loo Lin School of Medicine, NUS.

- A catheter robot for semi-autonomous cardiac ablation
Catheter ablation is a widely used minimally invasive procedure to treat arrhythmias when medications are unable to restore the normal heart rhythm. However, this is a highly skilled procedure, requiring extensive training, and may take many hours for a single procedure even in the most experienced hands. Robotics technology provides promising solutions to increase the accessibility of this treatment modality, and to assist training. However, existing robotic solutions remain unable to reduce the procedure time notably and the associated high cost precludes their widespread use. To address the above issues, in a new catheter steering robot for ablation procedures are being developed at King’s College London. This talk introduces the design of the catheter robot, the semi-autonomous catheter navigation control, and the contact force estimation based on shape tracking. The initial results show that robot can improve the current catheter ablation procedure in terms of both reducing the procedure time and increasing the ablation accuracy, with cost-effective design features.
Hongbin Liu is currently a lecturer (Assistant Professor) in the Centre for Robotics Research, Department of Informatics, King’s College London, UK, where he is leading the Robotic Contact Perception Lab. He received his B.S. degree in 2005 from the Northwestern Polytechnique University, Xi’an, China, and received MSc in 2006 and PhD degree in robotics in 2010 both from Kings College London, UK. He is a member of IEEE and Technical Committee Member for IEEE EMBS BioRobotics. His research is focusing on enriching the robot’s perception of during medical interventions, and making use of the augmented perception to enable quicker, safer, procedure. Applications of his research include soft tissue palpation during minimally invasive surgery, interventional cardiology and endoscopy.

- A Single Port Robotic System with parallel kinematic arms for rectal surgery
Single-Port surgery is an innovative technique and the next step in minimally invasive surgery. Performing complex surgical procedures through only one single incision or a natural orifice is a challenging task that could be simplified by involving surgical telemanipulators. Throughout the last decade, several single-port robots where introduced. While most of these system use cable driven continuum robots to set up the intracorporeal arms the FLEXMIN device uses miniaturized parallel kinematics instead.
This talk introduces the surgical telemanipulator FLEXMIN and focuses on the design and characterisation of the parallel kinematics. Because the telemanipulator will provide haptic feedback, the results of a first realized sensor concept that uses distally located force sensors to measure the tip force is presented.
With the manufactured prototype, complex surgical procedures like suturing and knot tying can be performed. Furthermore, it is shown that this approach is capable of applying high payloads exceeding 5 N and generating dynamic movements with speeds of more than 320 mm/s and accelerations beyond 1 G.
Because of the rigidity, excellent controllability and low latency the manipulator can perform high dynamic movements with the potential to compensate the movements of organs.
Sebastian Matich received his diploma in Electrical Engineering and Information Technology from Technische Universität Darmstadt, in 2011. He is currently working as research associate at the Institute of Electromechanical Design. His main research topic is the development of small scale parallel kinematic structures for use in surgical robotics. Additional research topics are precision engineering, small drives and sensor design.

- Steering Flexible Instruments using Fiber Bragg Grating Sensors
Flexible minimally invasive surgical instruments can be used to target difficult-to-reach locations within the human body. Accurately steering these instruments requires information about the three-dimensional shape of the instrument. In this talk, we use an array of Fiber Bragg Grating (FBG) sensors to reconstruct the shape of flexible instruments, and to robotically control the instrument. FBG sensors have several advantages over existing imaging modalities, which make them well-suited for use in a clinical environment. First, an array of FBG sensors is integrated on a Nitinol wire (1 mm diameter). A bevel tip is made on the tip of the shape sensing wire, such that a flexible needle is realized which bends during insertion into tissue. This needle with FBG sensors is inserted into biological tissue, and the resulting deflected shape is reconstructed and compared with camera images. Next, the needle is used as a stylet in a novel needle design with a tendon-driven actuated-tip. Kinematic models of the needle are combined with the needle pose reconstructed from FBG sensors to steer the needle in soft-tissue simulants. FBG-based shape sensing has also been used for the control of tendon-driven continuum manipulators. We control the position of the tip of a single-segment manipulator. This is followed by a case where we use FBG sensors to control the shape of a planar manipulator with two segments. In this case, the reconstructed shape was used for both obstacle avoidance while steering the manipulator tip along a pre-defined path. Finally, we demonstrate that continuum manipulators along with FBG sensors can be used for intrinsic force sensing.

- Robot-Assisted Laser Microsurgery: Overcoming Translational Barriers
This talk will present an overview of technology research, development and innovation activities in robot-assisted laser microsurgery at IIT. Lasers are being increasingly used in operating rooms as precision surgical tools for delicate surgeries on both soft and hard tissue. Applications range from fetal surgery to orthopedics, with significant examples in ophthalmology and laryngology. However, current clinical technologies do not properly support the accurate and intuitive use of lasers for high-precision high-quality microsurgeries, imposing severe challenges to the operations. To improve on this, new surgical robotic technologies and capabilities are being developed at IIT. Robot assistance is particularly suited and desired for laser microsurgery applications. Recent results prove they can augment the sensing and actuation capabilities of microsurgeons, allowing significant improvements in terms of surgical site accessibility and visualization, laser controllability, safety and surgical quality. Nevertheless, translating robotics research results to clinical practice is a long and challenging process in itself, involving a continuous refinement process with many system redesigns and simplifications. This talk will conclude presenting the IIT experience in this last phase, which is bringing microsurgical robotic systems closer to clinical trials.

- Robotic methods for insertion of flexible needles
A flexible needle has been recently introduced and improved for drug delivery and diagnosis. The flexible needle is made with a bevel tip so that it forms a bending curve as it is inserted into soft tissue. This enables to steer the needle by rotating and inserting. For the automatic control, the kinematic model and path planning for the needle insertion are developed. To capture and utilize the uncertainty in the needle insertion, a stochastic modeling technique is applied to a nonholonomic model for the flexible needle. The nonholonomic stochastic model is then used for the probability-based path planning. In this talk, a novel design idea and a new planning method for improved needle manipulation are also discussed.

- Medical robot and navigation system using intraoperative information system for minimally invasive surgery
Endoscopic surgery is now very popular as a form of minimally invasive surgery in which surgeons perform the operation using forceps and an endoscope through trocar. However, while this surgery has lots of merits, there are disadvantages that the working flexibility and field of view are limited. To overcome this, we have developed information based robotic system. Intra-operative sensing information offers the right target position during surgery and also surgeon can confirm the reliability of the treatment. Then the robot can be controlled based on the accurate prediction of the biological response against the operation.
In this talk, we will present the our recently developed robotic system and navigation system using intraoperative sensing information including vascular information based on ultrasound image and image mapping system for fetus surgery and force measurement system.
